I don't see any story either on the CDC site regarding this, at least in this month's press releases:
CDC Media Relations Home Page
There was a salmonella outbreak listed here, but no mention at all of dog food:
CDC is collaborating with public health officials in multiple states across the United States and with the U.S. Food and Drug Administration (FDA) to investigate a multi-state outbreak of Salmonella Agona infections. An investigation that includes interviews of persons with Salmonella Agona infections and comparison of the DNA fingerprints suggests that cereal from Malt-O-Meal unsweetened Puffed Rice Cereals and unsweetened Puffed Wheat Cereals is likely related to these illnesses.
As of May 13, 2008, state and city health departments from 15 states have identified 28 ill persons infected with same genetic fingerprint of Salmonella Agona. Ill persons with the outbreak strain have been identified from Colorado (1), Delaware (2), Illinois (1), Maine (4), Massachusetts (2), Michigan (1), Minnesota (1), North Dakota (1), New Hampshire (2), New Jersey (5), New York (3), Ohio (1), Pennsylvania (2), Rhode Island (1), and Vermont (1). Onset dates, which are known for 23 patients, ranged from January 1 to April 10, 2008. Patients’ ages ranged from 4 months to 95 years with a median age of 65 years. Eight hospitalizations and no deaths have been reported.
